I guess this assumes that they'll always be a newline after `"use strict";`?

[kzar, 2016/03/17 13:56:47]

Nit: Mind wrapping this long line?

As well as it assumes that double quotes are used, that there is a semicolon,
and no redundant whitespaces. These assumptions are safe because the code has
been rewritten and normalized in that process.

Done.

                'return exports;\n' +
                '})();\n';
     _print(js_beautify(code, options));
